CLAYTON WOLCOTT, OF HARTFORD, CONNECTICUT.

FASTENER FOR THE MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 487,314, dated December 6, 1892.

Application filed May 26, 1891.

To all whom it may concern:

Be it known that l, CLAYTON WoLooTr, of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Window-Fasteners, of which the following is a full, clear, and exact description, whereby any one skilled in the art can make and use the same.

The object of my invention is to provide a window catch or fastener having features of construction that enable it to be secured against opening except by a person within the building, and also to provide against the cutting away or wearing of the meeting-rails of the sash in operating the fastener.

To this en d my invention consists in the details of the several parts making up the fastener as a whole and in the combination of such parts, as more particularly hereinafter described, and pointed out in the claims.

Referring to the drawings, Figure 1 is a detail top view of the fastener, shown as secured to the meeting-rails of a window. Fig. 2 is a detail view, in vertical section, through the device or plane denoted by line of Fig. 1. Fig. 3 is a detail bottom view of part of the fastener. Fig. 4 is a top view of the base-piece. Fig. 5 is a detail bottom view of the swinging catch with the cover-plate removed. Fig. 6 is a detail side View of a modified form of catch with its side wall broken away to show construction.

In the accompanying drawings the letters a and b denote the meeting-rails of two window-sashes, and c the fastener that is secured to the upper surface of the meeting-rail a, that is a part of the upper sash of a window. The base-piece d is secured to the rail, as by means of screws, in the ordinary manner, and to this base-piece is pivoted the swinging catch c, that is provided on its under side with a hook or shoulder c', that is adapted to be swung into engagement with the edge of the striking-plate f, that is secured, as by means of screws, to the top of the meetingrail of the lower sash. This striking-plate has an extension from one edge, forming a guard f', that projects beneath the path of movement of the outer end of the catch, the hook or shoulder on which engages the guard and forces the two sashes into the proper Serial No. 134.467, (No model.)

against the edge of the rail when the windows are being fastened.

The base-piece d, to which the catch e is pivoted, is provided with a guide-slot d and locking-sockets d2, that serve to receive projections from the underneath side of the catch. The projection @2 is located in the slot CZ and aids in preventing any sliding movement of the catch. The locking-sockets d2 are adapted to receive a projection g on the under side of the bolt g, so as to lock the latch in position lengthwise of the rail to which it is pivoted and also in a position at right angles to the rails. The catch e is hollow and open on the under side, the opening being closed by a cover-plate h, being preferably provided with a fulcrum h', on which the bolt g is supported in such manner as to enable it to be given a tilting motion in a vertical plane. That end of the bolt overlying the base-piece is heavier than the outer portion, so that the bolt tends normally to drop into position for the lug g to engage either of the sockets cl2 that may be at the time below it. On the outer end of the bolt is supported a push button or pin t', arranged in a socket in the outer end of the catch in such manner that by pushing down on this button the inner end of the bolt will be lifted and the catch unlocked, so as to enable it to be swung into or out of engagement with the striking-plate.

The form of device shown in Figs. l to 5 is the one preferred, as it affords a form that is of comparatively-cheap construction both as to material used and time and labor consumed in finishing the device.

In Fig. there is shown a modified form of the fastener, in which the bolt gis pivoted to the coverplate by means of a pin passing through lugs upturned on the sides of this plate and through the bolt. A coiled spring j is also shown in position to aid the bolt in its normal tendency to engage the projection on the bolt with the sockets in the base-piece.

2. In combination, in a,WindoW-fastener, a@

base-plate, a swinging catch pivoted thereto, and a striking-plate having a-guard extending from the Side adjacent to theedge of the meetingrail and underlying the path of movement of the outer end of the catch, all substantially as described.

3. In a Window-fastener, in combination with a base-piece having locking-sockets in itsV upper surface, a Chambered swinging catch pivoted to the base-piece and open on the under lside, a cover underlying said opening and having a fulcrum for a tilting bolt, the ltilting bolt supported Within the catch and having a lug held normally in engagement with a looking-socket in the base-piece,

the push-button engaging the outer end of v the-bolmthe catch-plate, and the striking g plate, all substantially as described.
